Aptech Africa South Sudan continues to drive sustainable development through innovative renewable energy solutions, with the successful installation of a solar-powered water pumping and irrigation system in the communities of Kabu and Lombur, Luri Payam. This project is designed to strengthen agricultural productivity, improve water access, and enhance livelihoods through clean and reliable solar energy.
Aptech Africa deigned, procured and installed a 2.22kWp solar water pumping system, strategically mounted above the water storage tanks to maximize efficiency and system integration. The system is powered by four high-efficiency 555W solar panels. To ensure optimal performance and durability, Aptech Africa used a Grundfos SQF 5-70N submersible solar pump, paired with a CU202 controller. This combination ensures consistent water delivery even under varying solar conditions, making it ideal for rural and off-grid environments like Luri Payam.
The solar water pump supplies water to twin elevated storage tanks of 10,000 litres per site, mounted at a height of 4.5 meters. This elevation allows gravity-fed distribution, ensuring adequate pressure to efficiently run the irrigation network without the need for additional energy inputs.
From the main outlet line, water is distributed through 16mm drip irrigation lines, fitted with a filtration system to prevent clogging and protect the integrity of the driplines. This ensures long-term reliability while reducing maintenance requirements for the community. The fertigation system allows nutrients and fertilizers to be delivered directly through the irrigation network to plant roots. This method significantly improves nutrient absorption, reduces fertilizer wastage, and promotes uniform crop growth.
By integrating fertigation with drip irrigation, farmers are able to Increase crop yields and quality, reduce water and fertilizer use, lower labor costs, and Improve soil health and sustainability. This precision-based approach empowers farmers to grow more with fewer resources—an essential advantage in regions facing climate and water challenges.
Each site is expected to benefit approximately 50 community members, directly supporting smallholder farmers and households. Access to a reliable, solar-powered irrigation system enables year-round farming, reduces dependence on rainfall, and enhances food security. The project’s impact extends beyond agriculture; reduced operational costs by eliminating fuel-powered pumps, improved resilience to climate variability, increased household incomes through improved crop production, and skills transfer and local capacity building in system operation and maintenance
Through this installation in Kabu and Lombur, Aptech Africa is reinforcing its commitment to delivering clean energy, water access, and climate-smart agricultural solutions across South Sudan and the region. Aptech Africa is helping build resilient livelihoods, strengthen local economies, and promote sustainable development for generations to come.
